' The invention krelates to dispensers operated by air pressure whereindifierent lubricating oils or other liquids are arranged to bedelivered from different'ones of a battery of receptacles therefor by-and upon the opening of anelevated discharge'valve for the selected receptacle. v r fAn'object of the inve'n't-ion isto provide a I dispenser-"of'the class described in which a plurality of receptacles is assembled in such a manner as to provide a truly unitary, and 3 particularly compact structure. v ,.Another object .ofthe invention is to provide a dispenser of the character described in which the receptacle elements thereof are of a standard structure'and are arranged to provide a unit of the-class described inwhich I the 'operating compressed air therefor is -lligure 'l is a central vertical section be preformed as separate members" of the unit.@ 7 "'1 ,A further object of the inventionis to provide a dispenser of the character described having no pipe or; other connections through the bottom. thereofwhereby" it is disposable anywhere on asuppQrting surface'without special provision'therefor. I Yet another object of the invention is -to applied in a particularly simple manner.

A still further object of the invention is to provide a dispenser of the character described'in which the various delivery pipes are disposed in a convenientaligned. relation and at the same time function tosecure the receptacle elements .in substantiallyffixed relation.

Still another objectof the-invention-isto' provide a dispenser of the character'fdescribed in which the" "various compartments providedarefof clifiering capacitiesp The invention possesses other objects :and features of advantage, soine' of which, with foregoing, will' be .set" ferth 'in the following descriptionof a preferred form of the invention which is illustrated in the accompanying drawings, in which:

through a unit embodying the invention.

Figure, .2 is, a reduced and somewhat diagrammatic planlvievw taken at the plane As herewith particularly disclosed, the present invention is embodied in a unit 3 which is built up of anested assembly of receptacle elements 4, 5, G'and 7 the exact number of said receptacles comprising the unit being generally immaterial. These I receptacles, it is noted, are progressively smallerand the inner receptacles 5, 6 and 7 are arranged to be entirely Within the space defined within the outerreceptacle 4c. The

compartment 8 provided by the innermost/- the actual sizes :of thevarious receptacles may be varied for predetermining the com partment" capacitie' I In he present embodiment of the invention, the various receptacles of which the unitis formed are'of similar section in plan, being cylindrical withltheir axes vertical. As shown, the inside diameters of the receptacles, beginning with the outermost receptacle 4:, are approximately in the con-' tinued'ratio of 4 to3 to 2' to 1 whereby the capacities of the'compartments 11, 10, 9 and Slare roughly in the ratioof 7 to 5 to 3, to 1, es the thickness of the receptacle Walls and bottoms 'being ig'nored. These ratios are, of

course, variable interms of the receptacle sizes, and. may be predetermined in accordance'with ,the demand for the difierent L liquids 'A, B,' G' and Dto'be dispensed. fThe variousreceptacles 4, 5,6 and 7, will now be noted,'lare respectively constructed I as individual barrel-like members having tubular side walls 13, 14,15 and 16 and bot- 95.

toms 1 7, 18, 19 and 20,.each of said bottoms beingin the form ofa circular disc provid ing anedge' flange portion for securing the. disc to the wall member, as by welding; I In this manner, the receptacles are arranged partment underlying the mouth of the air V "to be cheaply and quickly made and are of a form in which they are particularly strong against "distortion or Other damage. It is v noted that the receptacle walls serve, in effect,to vertically partition the space of the outer receptacle and such walls do not, of course, intersect; 4 7 f 1;;The outer receptacle l is provided with-a ead in the form of a plate 22, which plate is provided with an upturned edge flange 33 for a fitted and sealed engagement with the v wall-13 adjacent the top edge thereof, said head being secured inpositlonfasby weldplane vadjacent,- but slightly; a spaced from,

in after the'various receptacles have been disposed in their desired nested relation.

,Delivery pipes j 28 are provided, said pipes extending upwardly through the head I .22 from points adjacent the bottomsof the H various compartments oftheuhit and be: ingprovided at their upper and outer ends with suitable delivery valves 24:. Capped filler pipes 25 are also providedin the head 22,.said' pipes preferably extending downwardly in the various compartments to points; below the ;top edges of the inner receptacles, which ledg es preferably define a the head 22. Thevarious'dehveryand filler pipes, it is noted,,are fixed in the head-in 3o,

sealed relation thereto, asfby welding It willnow be noted that the. common space defined "above the surfaces" of the liquids in the various 'compartments arrangedtocontain air under pressure, whereby, when anyone of the valves 24 s opened,

liquid from its associated compartmentw-ill be automatically and immediately di'se charged therefrom." i

Means are accordingly provided for sup? plying compressed air to said space'a d for automatically maintaining the required pressure therein. :As'shown, the necessary connection witha- 'source of compressed air is provided'through a pipe 26 extending through a wall of'the receptacle and dis- 7 charging above the plane of the upper receptacle edges; Preferably, and as shown, the pipe 26 is mounted on and extends through the head22, it 'now being, noted that all of the necessary pipes for the structure are carried by saidheadand may be 1 mounted thereon before the $2,111,818 fixed I in its operative position in theunit, lnithis manner, the air will not be dischargedthrough the liquidleven though the compipe is full, the filling limit being, ofcourse,

'the aforesaid plane of the top edges of the under-receptacles, If the pipe 26 is to be connected with a high-pressure compressor,

v an automatically operating pressure rereducer and serv cevalve mechanism would be interposed in said pipe, such being indicatedat 28.

With plurality of delivery pipes 23pmvidedin connection with abattery of re-"v ceptacles, as in the presentfinstance, it will usually be desirable that at least the protruding portions of "such pipes be spaced apart and preferably be aligned in a comthe disposal of the receptacles in position proper registration withthe filler pipes 25 "must be maintained, and such is accomplished by so disposingthe delivery and I V filler pipes that they cooperate to securefthe receptacles. in ftheirjarequired positions.

though loose in the; outer receptacle 4, are held inproper' operative relation to the filler pipes.

Prererably, and asshow-n, the r'el'ationlof the pipes is such as to" permit some relative movement of the receptacleswhereby the necessity for-an exact fitting of the pipes to. I
